Animals like crocodiles have different  ways of moving depending on their body structure, how their bodies work, and how they have evolved over time.

Crocodiles have a special way of walking that is affected by how their legs are built and where they live. They can move smoothly both in water and on land.

This unique way of walking is a result of their evolutionary adaptations for life in aquatic and semi-aquatic environments. In water, crocodiles use powerful tail movements for propulsion, and on land, they can move swiftly and silently to capture prey or protect their territory.

C because weight has the force of gravity pulling you down

The theoretical yield of ethyl chloride, given 27.17 g of ethylene and 58.33 g of hydrogen chloride, is 62.67 grams.

The first step in calculating the theoretical yield is to find the number of moles of each reactant. Given the masses and molecular weights, we find that there are 0.97 moles of ethylene and 1.6 moles of hydrogen chloride. The balanced equation shows that the reaction occurs in a 1:1 ratio, so the limiting reactant is ethylene as we have less of it.

The theoretical yield is therefore based on the amount of ethylene. Given the molar mass of ethyl chloride (64.5 amu), the theoretical yield would be the number of moles of ethylene multiplied by the molar mass of ethyl chloride. Therefore, the theoretical yield of ethyl chloride is 62.67 grams (rounded to the nearest hundredth without units).

The theoretical yield of ethyl chloride from the reaction of 27.17 g of ethylene with 58.33 g of hydrogen chloride is 62.61 g. Ethylene is the limiting reactant, and the yield is calculated using its moles and the molar mass of ethyl chloride.

To calculate the theoretical yield of ethyl chloride, we need to first determine the limiting reactant between ethylene and hydrogen chloride. We then use stoichiometry to find how much product can be formed from that limiting reactant.

First, calculate the moles of each reactant:

The stoichiometry of the reaction is 1:1, so:

Since we have more moles of HCl (1.5981 mol) than ethylene (0.9706 mol), ethylene is the limiting reactant. Now, we calculate the theoretical yield based on the moles of ethylene:

Theoretical yield of ethyl chloride (CH3CH2Cl) = 0.9706 mol * 64.5 g/mol = 62.6137 g

Therefore, the theoretical yield of ethyl chloride is 62.61 g when rounded to the nearest hundredth of a gram.

Explanation:

It will have 27 neutrons and protons because the atomic number is the same as the number of neutrons and protons.

The molecular weight is 18, and 16 of that is oxygen.  

So, water is 16/18 * 100 = 88.9% oxygen by weight.  

None of the other compounds have as high an oxygen content (by weight) as water.  

This is a trick question, and the University Chemistry grad fell for it.  

If you have the same weight of each compound (let's say, 10 grams, for example), then H2O has the most oxygen weight (8.89 g).

Answer:

This question is incomplete. The completed question is below

Which of the following compounds has the highest oxygen content, by weight? a. NaO b. CO c. BaO  d. H₂O

The correct option is d. H₂O

Explanation:

The percentage of oxygen by weight in NaO is

atomic mass of sodium (Na) is 23 g/mol while that of oxygen is 16 g/mol

molar mass of NaO = 23 + 16 = 39g

% by mass of oxygen  = 16/39 × 100 = 41.03 %

The percentage of oxygen by weight in CO is

atomic mass of carbon (C) is 12 g/mol while that of oxygen is 16 g/mol

molar mass of CO = 12 + 16 = 28g

% by mass of oxygen = 16/28 × 100 = 57.14 %

The percentage of oxygen by weight in BaO is

atomic mass of barium (Ba) is 137 g/mol while that of oxygen is 16 g/mol

molar mass of BaO = 137 + 16 = 153g

% by mass of oxygen = 16/153 × 100 = 10.46 %

The percentage of oxygen by weight in H₂O is

atomic mass of Hydrogen (H) is 1 g/mol while that of oxygen is 16 g/mol

 molar mass of H₂O = (2 × 1) + 16 = 18g

% by mass of oxygen = 16/18 × 100 = 88.89 %

From the above calculations, it can be deduced that H₂O has the highest oxygen content by weight

Final answer:

The number below each element's symbol on the periodic table refers to the atomic mass, which is different from the atomic number indicated by a subscript to the left of the symbol.

Explanation:

The number below each element's symbol on the periodic table represents the atomic mass of the element. This is different from the atomic number, which is represented as a subscript to the left of the element's symbol. Every element has a distinct symbol, typically the first one or two letters of its name, and the atomic number above each symbol in the periodic table indicates the number of protons in each element. For example, the element Carbon (C) has the atomic number 6, indicating it has 6 protons, and its atomic mass is shown beneath the symbol on the periodic table.

Final answer:

Using the balanced chemical equation [tex]2 ZnS + 3 O2 - 2 ZnO + 2 SO2[/tex], it is calculated that 2.7 moles of O2 can produce 1.8 moles of zinc oxide.

Explanation:

To determine how many moles of zinc oxide can be produced from 2.7 moles of oxygen, we need the balanced chemical reaction involving zinc and oxygen forming zinc oxide. The relevant equation is: [tex]2 ZnS + 3 O2 - 2 ZnO + 2 SO2[/tex].

From the equation, we can see that 3 moles of oxygen react to produce 2 moles of zinc oxide. Therefore, if we start with 2.7 moles of oxygen, we can use a simple ratio to find the number of moles of zinc oxide produced:

3 moles of O2 produce 2 moles of ZnO.

2.7 moles of O2 will produce (2.7 moles O2 * 2 moles ZnO / 3 moles O2) = 1.8 moles of ZnO.

Thus, 1.8 moles of zinc oxide will be produced from 2.7 moles of oxygen.

Answer:

The density of air goes down as you get higher with altitude.

Explanation:

Less air is pushing down on the molecules below it as you go up. This means that it is not as compacted, another word for which is dense.

The density of the air decreases with the increasing elevation (altitude).

Altitude is the height or distance measured in the up or vertical direction.

The higher the elevation, the less dense the air will be.

There are two reasons for this:

There is less air pushing down from above at higher altitudes, and gravity is weaker further away from the Earth's center.

As a result, air molecules may spread out more at higher altitudes, and air density drops.

Thus, As you go higher, the density of the air drops.

Explanation:

Final answer:

The law of mass action states that the equilibrium constant must be equal at equilibrium.

Explanation:

The law of mass action states that at equilibrium, the ratio of the concentrations of the products to the concentrations of the reactants is constant. This constant is known as the equilibrium constant (Keq), and it must be equal at equilibrium. The equilibrium constant expression is based on the balanced chemical equation for the reaction and relates the concentrations of the products and reactants.

Over millions of years the layers of sediment become squashed and form sedimentary rocks. The shells of dead marine organisms fall to the sea bed and become part of the sediment. Marine organisms used the dissolved carbon dioxide to make calcium carbonate for shells. Carbon dioxide dissolved in the oceans.

Final answer:

Carbon is locked up in sedimentary rocks through the burial and transformation of organic material from living organisms into fossil fuels and organic-rich rocks like shale and carbonate rocks such as limestone.

Explanation:

Carbon becomes locked up in sedimentary rocks through a series of processes that are part of both the biological and geological carbon cycles. In the biological cycle, living organisms, mainly plants, consume carbon dioxide from the atmosphere to build their tissues. Upon death, this organic material may be buried under sediment and over millions of years, transform into fossil fuels like coal, or become part of organic-rich shale and limestone.

Carbonate rocks like limestone primarily form through the accumulation of marine organisms' calcite shells. The weathering of rocks on land also releases carbon to the soil, which can eventually become part of sedimentary layers. Over time, the carbon from these processes becomes compacted and cemented into sedimentary rocks, thereby locking the carbon away for prolonged periods, typically ranging from tens of millions to billions of years.

The correct answer is - C. Warm water is carried to cooler parts of the ocean.

The Gulf Stream is warm ocean current. It is an ocean current that originates from the Caribbean region, where it is constantly warm throughout the year. Because of that, the water is warm as well, and since the warm water is less dense, it moves on the surface. The movement is toward the higher latitudes, where this current, as a surface movement of the water, is bringing warmer water to the cooler areas, such as the eastern coast of the United States. Not only that warm water is brought to these areas, but the Gulf Stream also brings in warm and moist air masses with it, making the climate much more mild, and increasing the amount of precipitation.

Answer:

Boiling point

Explanation:

If you want to find the boiling point of an unknown liquid, just use beaker, a hot plate, and a temperature probe.

Boiling is characterized by the rapid transition from liquid to gaseous, with the formation of vapors (bubbles) inside the liquid. As in fusion, there is a temperature (boiling point) at which a given substance changes from a liquid to a gaseous state. This temperature is the boiling point.

In the case shown in the question above, you will need to pour the liquid into the beaker and heat it up with the hot plate. With the temperature probe, you will mark the temperature that the liquid started to boil.

Mass of silver nitrate = 320.0 g × 0.75

                                    =  240.0 g

Molar mass of silver nitrate =  169.87 g/mol

Therefore;

Moles of silver nitrate = 240.0 g/169.87 g/mol

                                    =  1.413 moles

Mole ratio of Silver nitrate to silver metal = 1 : 1

Therefore, moles of silver metal = 1.413 moles

Hence;

Mass of silver metal = 1.413 moles × 107.868 g/mol

                                 = 152.40 g

To determine the amount of silver metal produced, use stoichiometry and the given information to convert the mass of silver nitrate solution to moles, use the mole ratio from the balanced equation to find the moles of silver, and then convert the moles of silver to grams using the molar mass of silver. The metallurgist can produce 152 grams of silver metal.

To determine the amount of silver metal that can be produced, we need to use stoichiometry and the given information. The balanced equation tells us that 1 mole of copper reacts with 1 mole of silver nitrate to produce 1 mole of silver. Therefore, we can convert the given mass of the silver nitrate solution to moles and then use the mole ratio to find the moles of silver produced. Finally, we can convert the moles of silver to grams using the molar mass of silver.

Step 1: Convert the mass of silver nitrate solution to moles using its molar mass.

Step 2: Use the mole ratio from the balanced equation to find the moles of silver produced.

Step 3: Convert the moles of silver to grams using the molar mass of silver.

Using these steps, we can calculate the amount of grams of silver metal produced, which is 152 grams.

Therefore;

when [H+] is 1 x 10^-7 then [OH-] will be;

= [1 × 10^-14]/[1 x 10^-7]

= 1 x 10^-7

When the [H+] changes from 1 x 10^-7 to  [1 x 10-4]

then the [OH-] will change from 1 x 10^-7 to;

 = [1 × 10^-14]/[1 x 10^-4]

 = 1 x 10^-10 M

Thus; the new [OH] is 1 x 10^-10 M
